I can upload my Joomla files using FTP and Install it
I uploaded it as a zip file and used aceba backup file "kickstart.php" to unzip remove and install via web.

I can upload pictures to media manager
All ok

What I can not do is to upload templates and modules.
I did however manage to install a small plugin,not sure why.
I am sure the modules and templates I install are not more than 1MB and the error comes with 10sec

When creating the website i tick off:
SuEXEC
Own Error-Documents
PHP -> FAST-CGI

I have problems understanding the whole permission thing depending on what "owns" the files but i through I had understood that if I uploaded the files with FTP and used FAST-CGI i should be able to use all Joomla functionallities like upload and install templates
